Hi There, I had a recent HBa1c test and was shocked to find that my blood sugar levels had gone up to 45. The last time I was tested was pre lockdown and it was 38 back in Oct 2019. I put the figure into the HbA1c Units Converter- DCCT to IFCC and was surprised to read that it said my blood sugar levels were still in the Green Zone. From memory normal is 20-41 and pre diabetic is 42-47 with diabetic 48 plus. Has the metre been re jigged or is it that I have a false memory on this ? I am doing everything I can to get my blood sugar levels down into the 20-41 range, including intermittent water only fasting and returning to a much stricter low carb diet. Any ideas on this ? And how can pre diabetic be regarded as good ?
